Emission technologies for environmental protection mandates
Diesel Oxidation Catalyst
• Removes up to 90% of carbon monoxide and hydrocarbons.
• High resistance to temperature.
• Provides heat for regeneration FPD, where applicable.
• Applicable for light and heavy.
Selective Catalytic Reduction (SCR)
• A post treatment solution for reducing NOx: A reducing agent
gas or liquid (generally ammonia or urea) reacting
NOx on the substrate to form water and hydrogen that are not
dangerous.
• Meets emission regulations in 2010
heavy commercial vehicles.
• Complies Euro-4, Euro-5 and Euro-6.
• Improves fuel economy indirectly, allowing
engine running hotter and lighter.
NOx catalytic absorption systems
• alternative to exhaust gas recirculation (EGR) and
selective catalytic reduction (SCR) NOx is absorbed in a
chemical tank, which then is converted into clean gas.
• collected NOx is converted to nitrogen clean (N²) dioxide
carbon (CO²) and water (H²O).
• good performance at high temperature exhaust.
• 90% the efficient conversion.
Diesel Particulate Filter (FPD)
• Filtration efficiency greater than 95%.
• High resistance to temperature.
• Complies Euro-4, Euro-5 and Euro-6.
• With regeneration.
sound engineering
• advanced predictive tools used by manufacturers
Top cars.
• Use tools such as predictive Gillaum, GT-Power
Wave.
